Title: Ski with better balance between running and climbing characteristics - has fine transverse serrations on running surface
Inventor: SCHNURRENBERGER HERMANN
IPC: A63C5/04
Filed: 1977-06-01
Abstract: The polyethylene running surface of a ski (4) has a number of fine transverse serrations which achieves a better balance between running and climbing characteristics of the ski. The region (5) to which the ski boot is attached has relatively coarse serrations. The regions (6) on either side of this central region have finer serrations. The serrations are formed by means of an abrasive belt with a coarseness standard of 30 as specified by DIN 69100 with a belt speed of 5 metres per second transversely to the ski axis. A finishing operation is carried out with a finer abrasive belt which moves parallel to the ski axis and removes any burrs and sharp edges.

Title: Electronic postal weighing scales - has parcel category and destination selectors with digital weighing platform
Inventor: GUDEAM DUMITRU CHICAGO
IPC: G01G19/00
Filed: 1977-06-28
Abstract: Mechanically coupled to a weighing platform is an optical transducer which feeds an encoder (14) to generate impulses corresponding to postal weight tariff increments. A first selector (30) sets the parcel category and a second selector (40) sets the destination zone. Signal corresponding to the settings are generated by further encoders (32, 42) coupled to these two selectors. Address generators (20, 34, 44) route the encoded data to a memory unit (50) which contains stored tariff data and converts the incoming data to a charge signal which is displayed on an indicator device (80). A falst zone detector (46) in combination with a blocking circuit (60) prevents an indication being given for non-permitted combinations of parcel category and destination zone. The blocking circuit is also controlled by a weighting platform null-load detector (18).

Title: Measurement and control for fluid flow valve position - is performed by logic circuit permitting energy consumption calculation
Inventor: LENZ KARL
IPC: F24D19/10
Filed: 1978-01-12

Title: Dual circuit brake pressure regulator - has respective coupled pistons with valves one having deceleration responsive by=pass
Inventor: BURGDORF JOCHEN DIPL ING
IPC: B60T8/28
Filed: 1978-05-12
Abstract: A control unit has two valves controlling respective rear brake circuits. The valves are coupled by a movable partition for pressure equalisation. One valve (12) is in a stepped piston (2) acting as a pressure reducing valve. The other valve is a pressure limiting valve (24). This valve has a by-pass (32, 33) with chamber (29) containing a deceleration responsive inertia ball valve (34). This prevents the pressure limiting from occuring too early in the event of failure or skidding. The partition may be a floating piston (3), which contains the pressure limiting valve, or two spring separated pistons.
Patent DE-2831670-A1 (DE)
Inventor: JAEGER GERD DR SC TECHN
IPC: G01B21/00
Filed: 1978-07-19
Abstract: Scanning elements in the form of photoelectric receivers (1) which can be displaced relative to the image of the intensity distribution (2) serve, on the one hand, to determine the coarse values and, on the other hand, the fine values. At the start of the measurement and after or during the measurement, the scanning elements (1) are positioned in known positions in relation to known equidistant reference points. The fine values are obtained by digital measurement of the relative distance between scanning element (1) and image of the intensity distribution (2). The coarse value is produced by counting coarse pulses, of which one is produced for each period in the intensity distribution (2). For a certain control direction of the tracking system, coarse and fine pulses are added in this direction with reverse signs to produce the measurement results. To prevent the scanning elements departing from the image segment, limiting contacts (16, 17) are fitted. This device is intended for application in optical measuring devices in which periodic intensity distributions occur. It makes possible an operationally reliable interpolation with a high degree of interpolation. <IMAGE>
